Newbie to site. Second GM truck

[Giftcurse]

I recently purchased a 2010 Sierra ext cab on Memorial Day. This is my second GM truck. My first was a single cab silverado with a full escalade conversion.

A week ago my truck was parked at work as usual. Same spot as always. I work for the city in Boston and a "runaway" bus rolled through the parking lot and rear ended my new sierra and pushed it into a building. 6 grand damage so far without a supplement. Needless to say I'm looking for the sierra denali nose and rear and HD hood. Any leads on parts would be appreciated.

Thanks guys!
